Cosmological Signatures of Dark Sector Physics: The Evolution of Haloes and Spin Alignment
Absem W. Jibrail, Pascal J. Elahi, Geraint F. Lewis
The standard cosmological paradigm currently lacks a detailed account of physics in the dark sector, the dark matter and energy that dominate cosmic evolution. In this paper, we co…
The imperative to reduce carbon emissions in astronomy
Adam R. H. Stevens, Sabine Bellstedt, Pascal J. Elahi +1
For astronomers to make a significant contribution to the reduction of climate change-inducing greenhouse gas emissions, we first must quantify our sources of emissions and review…
Extracting galaxy merger timescales I: Tracking haloes with WhereWolf and spinning orbits with OrbWeaver
Rhys J. J. Poulton, Chris Power, Aaron S. G. Robotham +1
Hierarchical models of structure formation predict that dark matter halo assembly histories are characterised by episodic mergers and interactions with other haloes. An accurate de…
Characterising the Structure of Halo Merger Trees Using a Single Parameter: The Tree Entropy
Danail Obreschkow, Pascal J. Elahi, Claudia del P. Lagos +2
Linking the properties of galaxies to the assembly history of their dark matter haloes is a central aim of galaxy evolution theory. This paper introduces a dimensionless parameter…
A Novel Scheme for Dark Matter Annihilation Feedback in Cosmological Simulations
Florian List, Nikolas Iwanus, Pascal J. Elahi +1
We present a new self-consistent method for incorporating dark matter annihilation feedback (DMAF) in cosmological N-body simulations. The power generated by DMAF is evaluated at e…
Multi-wavelength consensus of large-scale linear bias
Hengxing Pan, Danail Obreschkow, Cullan Howlett +4
We model the large-scale linear galaxy bias as a function of redshift and observed absolute magnitude threshold for broadband continuum emission from the far inf…
